How this service works
Guardian Handshake — two Passports (or two Solana addresses), one compatibility brief. Score delta, risk mismatch, overlapping patterns. Patterns, not verdicts. Agent guide: https://cyre.dev/SKILL.md
Output
Returns a JSON object with an 'ok' boolean, a 'kind' string identifying the result type, a 'brief' natural-language compatibility summary, a 'delta' object containing the score difference and risk mismatch details, and a 'disclaimer' noting these are patterns rather than verdicts.
Example use cases
Pre-trade counterparty compatibility check
“Before I settle this OTC deal, run a Guardian Handshake between my wallet 7xKp...aB3 and the counterparty at 4mNq...rW9 and tell me if there's a significant risk score gap or overlapping risky patterns.”
Agent-to-agent trust verification
“I'm about to let two of my agents interact on-chain — check their Solana addresses DKm2...xP1 and 9nQr...eL5 against each other in a Guardian Handshake so I can see if their behavioral profiles are compatible.”
Multi-sig partner vetting
“We're adding a new co-signer to our multi-sig — can you do a Guardian Handshake comparing our existing signer's Passport with the new candidate's address FpT8...sJ2 to surface any risk mismatches?”
Technical details
Endpoint
GEThttps://cyre.dev/api/handshakeWhen to prefer
Use this endpoint when you need to compare two specific counterparties — via Guardian Passports or raw Solana addresses — and want a structured compatibility brief with quantified score delta and pattern overlap. Prefer this over single-address endpoints when the key question is the relationship or mismatch between two parties rather than the absolute risk of one. Best suited for pre-settlement, pre-trade, or agent pairing scenarios where bilateral compatibility matters.
Side effects
- Missing both tokenA/tokenB and addressA/addressB — returns error requiring at least one pair of identifiers
- Invalid or expired Guardian Passport tokens — returns error indicating invalid attestation
- Unrecognized Solana address format — returns validation error
- Address with no on-chain history — may return minimal or inconclusive brief
- Payment not received (x402) — returns 402 Payment Required before processing
